Semi-hermetic, suction gas-cooled 8-cylinder reciprocating compressor in
compact design with optimized valve plate system “mexxFlow”. “mexxflow” is a
highly efficient and reliable valve plate system with higher refrigeration
capacity at lower power consumption. The compressor shows best possible
serviceability (e.g. by means of a replaceable drive motor), outstanding running
comfort and efficient operating performance. The suction cover can be rotated by
90° in each instance. Dependable mechanism lubrication is guaranteed by means of
an oil pump which is independent of rotating direction, as well as a
large-volume oil sump. The optional oil sump heater is using an immersion sleeve
and can therefore be replaced without intervening in the refrigeration cycle. A
direct connection facility for an oil level regulator is possible on one of the
three standard sight glasses. The large-volume electric terminal box in solid
metal design has easy quick-release fasteners. The electronic motor protection
INT69G uses PTC sensors to monitor the winding temperature (as standard
equipment) and optional the discharge gas temperature.

| 5) | Declared dual-number noise emission values are in
accordance with ISO 4871. The corresponding uncertainty to the sound power level
is KWA = 2,5 dB and to the sound pressure level is KpA =
2,5 dB. The values are valid for 50 Hz with the refrigerant R404A at the
standard rating points according to EN 12900.
- A-weighted sound power level LWA (re 1 pW), in decibel. To
determine the values, measurement methods of the ISO 3740 standard with
accuracy class 2 or higher were used .
- A-weighted sound pressure level LpA (re 20 µPa), in decibel.
The values are calculated from the sound power level in accordance with ISO
11203: LpA = LWA - Q2 at a distance of d = 1m
to the reference box.
